Abstract
Glomus tumours (GT) are mesenchymal tumours composed of modified smooth muscle cells of the glomus body. It commonly occurs in skin and soft tissue of the distal extremities. Gastric GT is a rare neoplasm of gastrointestinal tract that frequently mimics other mesenchymal neoplasms clinically and radiologically. We report a case of glomangioma of gastric antrum in a 55-year-old female, mimicking gastrointestinal stromal tumour (GIST) endoscopically. Radiographically, tumour was intramural, 6 cm in size, and initial biopsy was inconclusive. Laparoscopic-assisted partial gastrectomy was done. Histopathological examination showed uniform round cells arranged around the blood vessels, a characteristic of glomangioma. Tumour cells were strongly immunoreactive for smooth muscle actin and h-Caldesmon and negative for desmin, cytokeratin, CD34, CD117 and chromogranin, which helped rule out other differential diagnoses. Recognition of this rare entity is important as most of them are benign and surgical resection is curative.
